I have just noticed that the "Radical" property in PropList.txt comprises :
2E80..2E99 ; Radical # So [26] CJK RADICAL REPEAT..CJK RADICAL RAP
2E9B..2EF3 ; Radical # So [89] CJK RADICAL CHOKE..CJK RADICAL C-SIMPLIFIED
TURTLE
2F00..2FD5 ; Radical # So [214] KANGXI RADICAL ONE..KANGXI RADICAL FLUTE
In UCD-4.0.0.html the explanation of the "Radical" property is "Used in
Ideographic Description Sequences".
The Yi Radicals (U+A490..A4CF) are modelled directly on the Chinese radicals,
and are used in exactly the same way as CJK radicals are (for indexing etc.).
Should they therefore be included in PropList.txt under the Radical property ?
If Yes, then the explanation of the "Radical" property in UCD.html needs
amending, as Yi Radicals cannot or should not be used in combination with IDCs.
If No, then maybe the "Radical" property should be renamed the
"Ideographic_Radical" property to make explicit its scope.
